In all honesty, you are going to hate me. I watch the dubbed versions. I just find them easier to relate to the characters. I know dubs usually are not done well or have awkward moments, but without the English language I don't relate very well to the characters.
I'd also like to mention that Samurai Champloo is fairly old. (For me; Like 2005ish)
You want help with anime but you watch dubbed? I'm afraid you're beyond help, friend.
Fucking hell, watching dubbed anime makes me feel like the protagonist in A Clockwork Orange when they fix his eyelids into perpetual upsprungedness while blasting him with drugs that make you fucking hate whatever's in front of you.
Seriously, if you watch dubbed anime there's something wrong with you.
Anyway, some suggestions (and for god's sake and all that is holy, fucking watch them with original audio):
Texhnolyze - Dystopian future where everything's gone to shit, featuring cool stuff like artificial limbs (in the series, this technology is called "texhnolyzing"). Main character is a pit fighter in a gladirorial like setting, where he starts his ascension from bottom of society, struggling with his ever growing apathy of human life and stuff that makes you feel really shitty. Watch if you like feeling shitty.
Afro Samurai and Afro Samurai Resurrection - In this instance I'm actually cool with the dubbed version, since Samuel L. Jackson stars in it. Reminiscent of Samurai Champloo with its hip-hop style, but way grittier with ultraviolent gore, superhuman beatings and fucking glorious fucked-up'edness in general. Very casual like with 5 episodes per series.
Well, you already watched Ghost in the Shell, very nice series, my all time favourite.
Eureka Seven - Kinda cheesy, protagonist is a bundle of sticks, but if you like mechas and surfing, and generally awesome animations, this is for you.
Code Geass - Decent anine, very ominous plot and dark enough for my personal taste. Watch if you like mechas (I'm a bit of a mecha fan, yes...), plot twists in every corner and fresh and original concept.
CLANNAD - You'd probably judge me for watching this, but I like dramas and this one will probably make you shed a few tears. Not an amazing anime, but it leaves you with a lasting impression (mainly because I cried like a little girl almost

).
FMA: Brotherhood - One of the few good animes out there, highly recommend.
Anything Miyazaki is always brilliant.
And if you want something completely different; Lucky Star - Just wach it, you either hate it or love it.
